Environmental impact of mining and beneficiation of copper …
The mining and beneficiation process of one tonne copper sulfide ore is listed as a basic functional unit. 0.03 tonnes copper concentrate, 0.14 tonnes high-sulfur concentrate, and 0.02 tonnes low-sulfur concentrate obtained from one tonne raw ore were performed based on the economic allocation principle.

Copper Beneficiation Process
Copper Beneficiation Process . Get A Quote. Introduction . Copper ore is divided into sulfide ore (oxidation rate less than 10%) and oxide ore (oxidation rate greater than 30%) according to the degree of oxidation. Most of the copper produced in the world comes from sulfide ores, and a small part comes from oxidized ores.

From Ore to Finished Product
Beneficiation of Copper Ore. The next step in processing is called beneficiation. This is the first step in concentrating the copper into a more useable form. 5. Smelting and Extraction. The next step in the process flow is smelting for sulfide ore concentrate and solvent extraction for oxide ore leach solution. 6. Refining.
